  1. Enabling web caching can mitigate the DoS attack on GET request. But another common type of DoS attack is to send huge amounts of data in an HTTP POST method. To mitigate this type of DoS, it is considered best practice to set the PostTimeoutSecs, MaxPostTimeSecs, MaxPostSize settings in your web server or application server. The parameter names vary across different servers. Thanks~ Anne from sdlc security training
